In one line
We’re looking for a senior engineer who builds software by directing AI agents rather than typing code, and who can lead a production SaaS platform that way.
 

About the project
The project is a SaaS platform for culture-first hiring. It matches candidates on skills and cultural fit using psychometric profiling, a matching engine and AI-assisted assessment. The product is built and about to launch with its first pilot customers.
 

How we build: fully AI-native
The project has been built from day one with Claude Code as the main development tool. Agents write most of the code. Humans set direction, define the rules, review the output and own the result.

Concretely, the codebase has:

• CLAUDE.md files and binding playbooks (security, frontend architecture, styling) that agents must follow
• About 20 custom Claude Code skills for planning features, backend and frontend development, testing, security review, CI, dependency audits and more
• Hooks and guardrails, for example blocking agent commits to protected branches
• Parallel agents running in separate git worktrees
• MCP integrations: Playwright for visual and end-to-end testing, Jira (the roadmap syncs to Jira through Claude), Claude Design, and an accessibility checker
   

The new hire won’t just use this setup. They’ll own it, improve it, and decide how future engineers and agents work together.
 

The role
This a lead technical hire. The person drives the platform from pilot to production and owns its technical quality. They’ll work closely with the team, who also builds with Claude Code daily. We want someone who takes real ownership and pushes back, while the team keeps the final say on product direction.
 

What they’ll own

• The AI-native workflow: skills, playbooks, hooks and agent orchestration, and making the agents produce better output over time
• Judgment over agent output: reviewing AI-written code at scale, catching what drifted, and blocking what shouldn’t be merged
• Production: taking the platform live and keeping it running (deploys, monitoring, incidents)
• Security and GDPR-safe handling of sensitive candidate data
• LLM features in the product: evals, consistency, cost, prompt-injection defence and fallbacks
• Pilot feedback: turning it into scoped work
   

Must-haves

• Builds with Claude Code or a comparable agentic tool as their primary way of working, every day, for at least 6 months
• Has written their own CLAUDE.md files, skills, subagents or MCP setups, and can show them
• Can explain where agents fail and how they guard against it (tests, review, constraints, isolation)
• 7+ years in web development, with senior or lead responsibility for a SaaS product in production
• Strong TypeScript, React and Node; solid PostgreSQL. Agents write the code, but the lead has to know when it’s wrong.
• Has shipped LLM features to real users
• Pragmatic, with business sense and a startup mindset
• Excellent English and clear async communication
   

Not a fit

• “AI experience” means Copilot autocomplete or pasting into ChatGPT
• Uses AI only for boilerplate and writes the “real” code by hand
• Accepts agent output without reading the diff or running it
   

Nice to have
HR tech, recruitment or ATS experience; GDPR or EU AI Act exposure; security hardening; BullMQ, Prisma, Railway or Vercel; experience mentoring or leading.
 

Stack
React 19, Vite, Fastify 5, Prisma, PostgreSQL, Redis/BullMQ, TypeScript, Vitest, Playwright, Vercel, Railway, Anthropic models via the Vercel AI SDK.
 

Setup

• Fully remote
• Full-time and long-term
• Contract: B2B only. The candidate must have their own registered business and invoice us directly every month.
• No employment contract, and no invoicing through an agency or outsourcing company

Our client is a fast-growing, well-funded startup building the AI-native ERP for modern finance teams. Every business needs a financial system of record, yet the world’s largest fintech market ($220B+) still runs largely on software from the 1990s. Their platform automates accounting from data entry all the way to close, so finance teams move faster, spend less and take on less risk.
 

In just two years they’ve raised $100M+ from top-tier venture capital and growth investors, and work with customers ranging from $5M ARR startups to publicly traded companies.
 

They hire outliers: people who have achieved difficult things, in their careers or beyond. The team includes former competitive athletes at the highest level of their sport, Broadway performers, people who trained with UFC champions, and the founder of one of the country’s largest Python communities.
 

This is a confidential search. The company name will be shared with shortlisted candidates ahead of interview.
 

Responsibilities

This is a hands-on, ship-things role.

• Embed on named customer projects and own them end to end: discovery, design, build, deploy and verify.
• Build migration and integration pipelines on Temporal that are idempotent, resumable and auditable.
• Model and load customer accounting data into Postgres correctly, including reconciling it against the customer’s existing system.
• Build internal tooling so recurring one-offs stop being one-offs.
• Feed patterns back into the core product, and productize or hand off anything that becomes permanent.
• Shorten the path from “customer requested” to “shipped”.
   

Requirements

• Hardcore work ethic and high agency.
• 5+ years shipping production full-stack software, end to end and unsupervised.
• Django and Django REST Framework.
• PostgreSQL beyond ORM defaults: you read query plans and have run migrations against live data with customers on it.
• Next.js and React with TypeScript.
• Durable workflow experience: Temporal preferred, Celery is fine.
• Direct customer exposure: you’ve sat with a customer, scoped the problem with them and shipped against it.
• Experience with third-party APIs, webhooks, rate limits and reconciling two systems that disagree.
• Strong spoken and written English.
   

Nice to have:

• Accounting, ERP or fintech knowledge: double-entry, chart of accounts, close, AP/AR, revenue recognition.
• Prior forward-deployed, applied or special-projects experience.
• Judgment about when to ship a script versus build a system.
   

Benefits

• Join early in one of the fastest-growing AI companies in finance and grow with it.
• Your feedback shapes the product directly.
• A high-speed, high-trust environment with high expectations.
• Remote-first team.
• 27 days of PTO including public holidays.
• Home internet, co-working space and office setup support.
• Unlimited AI token usage.
• AI skills development and enablement.
• Learning and development budget for courses, certifications and language learning.
• In-person team meetups.

• Strong Python and Django / Django REST Framework experience, or deep experience in a closely comparable backend stack.
• Strong React and TypeScript experience, with the ability to work effectively across backend and frontend when required.
• Strong PostgreSQL and data modeling skills. You should be comfortable designing schemas that can evolve as the business grows into new products and safely changing them once they contain production data.
• Production experience with asynchronous and distributed workloads using Celery or comparable technologies.
• Strong understanding of API design and third-party integrations, including failure handling, retries, idempotency, data consistency, reconciliation, and situations where the system on the other side is unreliable or outside your control.
• Strong understanding of software architecture and the ability to make pragmatic architectural decisions inside a large existing codebase rather than only designing systems from scratch.
• Experience identifying and addressing performance, scalability, reliability, and maintainability problems before they become critical.
• Strong testing practices and experience safely evolving systems that must remain operational while they are being changed.
• Production experience with Docker, CI/CD, monitoring, error tracking, and observability. 
• Strong Linux knowledge. 
• Sound judgment about technical debt: knowing the difference between an acceptable shortcut and one that will create significant problems later, and being able to improve a system while it remains in production.
• Everyday experience with using AI agents for work (Claude Code or Codex). Familiar with configuring AI toolset, understanding pros and cons of modern AI.

Current Stack

• Django / DRF, PostgreSQL, Redis, Celery, Docker, Traefik, Datadog, Sentry, Mailgun, GitHub Workflows.
• Next.js, MUI, TanStack Query, React Hook Form, Zod, Vitest.

Nice to Have

• FinTech or financial systems experience, particularly payments, payouts, ledgers, reconciliation, payroll, banking, audit trails, or other systems where financial correctness matters.
• Experience with restaurant or hospitality technology, including POS, scheduling, workforce management, payroll, or similar systems.
• Experience with high-volume or business-critical third-party integrations.
• Experience improving a system with meaningful legacy code or technical debt while the product remained actively developed.
• Experience with multi-tenant SaaS architectures.
• Experience improving engineering practices across a team rather than only within your own work.
• Experience as a Senior Engineer in a company of roughly 20–200 people, where your role included helping decide what technical work actually mattered.

Required Soft Skills

• Ability to take technical ownership beyond your own tickets and think about the health of the product and engineering system as a whole.
• Strong engineering judgment and the confidence to challenge technical decisions constructively, including decisions made by Staff Engineers and engineering leadership.
• Comfort with ambiguity. Problems will not always arrive fully specified, and part of your job is asking the questions that make them clear before code gets written.
• Ability to explain complex technical trade-offs clearly to engineers, Product, and non-technical stakeholders.
• A strong teaching mindset. You explain your reasoning, document important decisions, review code seriously, and make the engineers around you better rather than becoming the only person who understands a difficult system.
• Comfortable taking leadership during difficult technical situations without waiting for someone else to define every step of the solution.
• Strong written communication and self-direction. The team is distributed across Canada and Europe with limited live overlap, so you need to communicate clearly asynchronously and drive your own work.
• Fluent English, written and spoken.

Key Responsibilities

1. Own substantial systems end to end

• Take meaningful problems that have been identified but not fully solved and work with Staff Engineers and Product to determine the right technical approach.
• Own complex initiatives from problem definition through design, implementation, migration, testing, rollout, and production monitoring.
• Design not only for the expected path, but also for what happens when something goes wrong in production.

• Remain responsible for the systems you build once they are carrying real customer data and real money.

   

2. Help strengthen the architecture of a growing product

• Work closely with Staff Engineers and the VP of Engineering on architectural decisions and technical direction.
• Understand the existing architecture and identify where today’s decisions may create tomorrow’s problems.
• Identify areas where the platform may struggle as product complexity, integrations, customers, data volume, and transaction volume increase.
• Challenge architectural decisions constructively when you see a better approach.

• Help evolve the architecture incrementally through small, safe improvements rather than unnecessary rewrites or over-engineering.

   

3. Protect correctness, reliability, and engineering quality

• Treat financial correctness as a first-class engineering concern.
• Design for reconciliation and auditability: how we prove a number is correct, understand how it was produced, and detect discrepancies before customers do.
• Use Datadog, Sentry, logs, production data, and other signals to identify recurring problems and their root causes.
• Improve observability, error handling, testing, deployment safety, performance, and operational reliability.

• Make sure recurring production problems are solved systematically rather than repeatedly patched.

   

4. Own technically difficult areas of the product

• Lead work involving complex third-party integrations, asynchronous workflows, data synchronization, reconciliation, migrations, and failure recovery.
• Design systems that behave predictably when external APIs fail, requests are duplicated, jobs execute late, or data arrives in an unexpected state.
• Work closely with Product to make technical feasibility and engineering constraints visible before implementation begins.

• Help break large technical initiatives into safe, incremental pieces that can be built, migrated, and released without unnecessarily putting the existing platform at risk.

   

5. Make the case for important technical work

• Identify technical debt, platform investment, reliability work, and architectural improvements that may not naturally appear on the product roadmap.
• Distinguish between debt that can safely remain and debt that is materially affecting reliability, engineering speed, or future product development.
• Make the business and technical case for that work using evidence rather than engineering preference alone.

• Help sequence improvements so they support product development rather than competing with it unnecessarily.

   

6. Raise the level of the engineering team

• Be a strong technical reference point for other engineers.
• Review architecture, designs, and pull requests with a focus on correctness, reasoning, and long-term maintainability.
• Explain why you would make a decision differently rather than simply leaving a verdict.
• Mentor engineers through reviews, pairing, technical discussions, and example.
• Document important knowledge and decisions so understanding stays with the team rather than with one individual.

• Take leadership when a difficult technical problem crosses multiple areas or engineers.

   

7. Remain hands-on

• Design and write production code across the backend and frontend.
• Take direct ownership of technically difficult or risky work when appropriate.
• Debug difficult production issues and establish their root causes.
• Read and understand the existing codebase before changing it.

• Build enough direct knowledge of the platform to ensure your technical decisions are grounded in how the system actually works.

   

Who this position is not for

• This is not a role for someone whose definition of seniority is simply delivering more complicated tickets. 
• If you prefer receiving clearly defined tickets and technical solutions and then implementing them, this role will probably be frustrating.
• It is not a management role. You won’t have direct reports or headcount responsibility. Leadership here comes through technical ownership, judgment, mentoring, reviews, and influence.
• It is also not a Staff Engineer role. Our Staff Engineers and VP of Engineering set the overall technical direction and architecture. You will help shape that direction, challenge it when needed, and fully own the design and implementation of substantial systems within it.
• It is not a greenfield role. You will be joining a live platform with thousands of customers and a roadmap that does not pause while technical improvements are made. Much of the work involves understanding existing systems, migrating them safely, and improving them incrementally rather than replacing them.
• If you naturally ask what happens when the system gets significantly larger, how it fails, how we know the data is correct, and what today’s shortcut will cost us a year from now, you’ll recognize the work.

Things You Should Know Before Applying

• The engineering challenge is no longer simply building features quickly. It is continuing to ship while improving reliability, scalability, architecture, and the technical foundation required for significant year-over-year growth
• There is technical debt. Part of your job is determining which debt actually matters, making its impact visible, and helping address it without stopping product development.
• Requirements will sometimes be incomplete. We expect you to help shape the solution rather than wait for perfect specifications.

• You will be expected to disagree when necessary, propose better approaches, and explain the reasoning behind them.
